pytest-coverage

SkillDev tools

Lets your agent run pytest tests with coverage and find lines the tests miss.

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the pytest-coverage skill

About this skill

Run pytest tests with coverage, discover lines missing coverage, and increase coverage to 100%.

What this skill tells your AI

The instructions your AI receives, as published by github/awesome-copilot in skills/pytest-coverage/SKILL.md and read by ahel’s review.

The goal is for the tests to cover all lines of code.

Generate a coverage report with:

pytest --cov --cov-report=annotate:cov_annotate

If you are checking for coverage of a specific module, you can specify it like this:

pytest --cov=your_module_name --cov-report=annotate:cov_annotate

You can also specify specific tests to run, for example:

pytest tests/test_your_module.py --cov=your_module_name --cov-report=annotate:cov_annotate

Open the cov_annotate directory to view the annotated source code. There will be one file per source file. If a file has 100% source coverage, it means all lines are covered by tests, so you do not need to open the file.

For each file that has less than 100% test coverage, find the matching file in cov_annotate and review the file.

If a line starts with a ! (exclamation mark), it means that the line is not covered by tests. Add tests to cover the missing lines.

Keep running the tests and improving coverage until all lines are covered.
